Polytetrafluoroethylene (PTFE) hoses are widely recognized as one of the most reliable fluid transfer solutions for demanding industrial environments. Thanks to their excellent chemical resistance, wide temperature tolerance, and long service life, PTFE hoses are extensively used in industries such as chemical processing, oil and gas, food & beverage, pharmaceuticals, automotive, and industrial machinery.

What Is a PTFE Hose?

A PTFE hose is manufactured using a PTFE inner tube, which is chemically inert and non-reactive, combined with one or more layers of external reinforcement. The most common reinforcement is stainless steel wire braiding (SS304 or SS316), providing enhanced pressure resistance, mechanical strength, and durability.

Depending on the application, PTFE hoses can be designed as:

• Smooth bore PTFE hoses

• Convoluted (corrugated) PTFE hoses

• Single or double stainless steel braided hoses

• Rubber-covered PTFE hoses for additional protection and safety

Key Advantages of PTFE Hoses

1. Outstanding Chemical Resistance
PTFE is resistant to almost all chemicals, including acids, alkalis, solvents, oils, and corrosive media. This makes PTFE hoses ideal for aggressive chemical transfer applications.

2. Excellent High-Temperature Performance
PTFE hoses can typically operate in temperatures ranging from -70°C to +260°C, making them suitable for high-temperature steam, hot oil, and thermal fluid systems.

3. High Pressure Capability
With stainless steel wire braiding, PTFE hoses can withstand high working pressures and pressure fluctuations, ensuring safe and stable operation even under demanding conditions.

4. Low Friction and Non-Stick Surface
The smooth inner surface of PTFE reduces flow resistance, minimizes pressure drop, and prevents material buildup, which helps maintain consistent flow and reduces maintenance requirements.

5. Long Service Life and Reliability
PTFE hoses do not age easily, crack, or become brittle, even after long-term exposure to heat, chemicals, and harsh environments. This significantly reduces downtime and replacement costs.

Common Applications of PTFE Hoses

PTFE hoses are widely used in various industrial systems, including:

• High-temperature steam and thermal oil pipelines

• Hydraulic and pneumatic systems

• Chemical transfer and dosing systems

• Fuel and lubricant lines

• Food, beverage, and pharmaceutical processing (with food-grade PTFE)

• Machinery requiring flexible, high-pressure fluid connections

Customization Options

To meet different working conditions, PTFE hoses can be customized in terms of:

• Hose inner diameter and length

• Single or double stainless steel braid

• Stainless steel grade (SS304 / SS316)

• External rubber or PVC covering

• End fittings (BSP, NPT, metric, flanged, quick couplings, etc.)

Custom-designed PTFE hose assemblies help ensure perfect compatibility with specific equipment and operating environments.

Conclusion

PTFE hoses offer an ideal balance of safety, performance, and durability for high-temperature and high-pressure applications. With their exceptional chemical resistance, wide temperature range, and customizable structure, PTFE hoses remain a preferred choice for industries seeking reliable and long-lasting fluid transfer solutions.

If you need custom PTFE hose assemblies or are looking for a dependable supplier, PTFE hoses provide a proven solution for even the most demanding industrial applications.
